This document assesses the risk associated with the dissemination of carbapenemase-producing hypervirulent Klebsiella pneumoniae (hvKp) of sequence type (ST) 23 and other STs in the European Union/European Economic Area (EU/EEA).
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 7-13 January 2024 and includes updates on SARS-CoV-2, measles, diphtheria, Middle East respiratory syndrome coronavirus (MERS-CoV) and poliomyelitis.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 26 November - 2 December 2023 and includes updates on human infection with influenza A(H1N2)v, influenza A(H5N1), an overview of respiratory virus epidemiology in the EU/EEA, respiratory infections due to Mycoplasma pneumoniae in the EU/EEA, HIV/AIDS surveillance 2023 (2022 data), West Nile virus, SARS-CoV-2 variant classification, and poliomyelitis.
Meningococcal disease is caused by Neisseria meningitidis, a bacterium with human carriers as the only reservoir. It is carried in the nose, where it can remain for long periods without producing symptoms.
Poliovirus is highly contagious and infected individuals shed virus in the faeces and from oral secretions, thus the mode of transmission is person-to-person, both via the faecal-oral and the oral-oral routes.
A joint study of the National Public Health Organization in Greece (NPHO) and the European Centre for Disease Prevention and Control (ECDC) conducted in 15 Greek hospitals in 2022 sheds light on the rapid spread of carbapenemase-producing, highly drug-resistant Klebsiella pneumoniae sequence type (ST) 39, following its initial documentation in a European-wide genomic survey in 2019.
The main aim of the genomic study described in this surveillance report was to determine the distribution of the highly drug-resistant clade of Klebsiella pneumoniae (sequence type (ST) 39 in Greek hospitals in 2022.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 22-28 October 2023 and includes updates on poliomyelitis, SARS-CoV-2, West Nile virus, the Rugby World Cup 2023, and cryptosporidiosis cases.
